Filter by:The treatment for fistula-in-ano (FIA) remains a challenge to General and Colorectal Surgeons Worldwide. A variety of surgical treatments have been described for high anal fistulas, but none offers the panacea of fistula eradication with guaranteed preservation of continence. This study compares Collagen paste injection to mucosal advancement flap for the treatment of fistula-in-ano.
Multicenter retrospective study of a cohort of patients affected by laryngeal carcinoma and subjected to total laryngectomy surgery at the centers participating in the reference period and responding to inclusion criteria.
The aim of this study is to evaluate the role of stellate ganglion blockade (SGB) for preserving arteriovenous fistula in hemodialysis patients undergoing major lower limb orthopedic surgery.
This observational study was conducted in patients undergoing elective pancreaticoduodenectomy or distal pancreatectomy. It mainly answers the following two main questions: 1. What are the risk factors for clinically relevant postoperative pancreatic fistula in different pancreatic surgeries? 2. What is the correlation between perioperative blood and interstitial fluid glucose level and clinically relevant postoperative pancreatic fistula in different pancreatic surgeries？ Participants were not required to perform additional research work other than the usual postoperative follow-up within 30 days after surgery. No control group was set in this study, and no additional clinical intervention was performed.
Multicenter, prospective, randomized study aimed at evaluating the difference in risk of PCF after salvage laryngectomy in two groups of patients: one cohort treated with Total Laryngectomy (LT) with primary suture, a second group treated with LT and reinforcement by flap positioning with onlay technique (PMM, ALT)
Pancreaticoduodenectomy is the standard surgical operation for benign or malign pancreatic lesions. Pancreatic Fistula (PF) or Postpancreatectomy Acute Pancreatitis (PPAP) are the major complications associated with that type of surgery. We need to develop preventive measures for these complications, which requires a better understanding of their physiopathology. The aim of this prospective monocentric and observational study is to identify predictive biomarkers and/or risk factors for PF or PPAP using metabolomics. The Profiling of circulating metabolites is indeed an original and promising approach for this purpose. We will also investigate the patient's immune status and its association with the occurrence of post-surgical complications. Participants will be adult patients scheduled to undergo elective pancreaticoduodenectomy. Surgery and patient's management will be as usual. During surgery, a fragment (0.1-0.2 g) of non-tumoral pancreatic tissue will be removed and frozen at -80°C for metabolomic analysis. For immunological assessment, 4 blood samples will be collected (before surgery and then 7 days, 1 and 3 months after, blood sampling).
Arteriovenous fistulas (AVF) are considered essential and the primary vascular access for end-stage renal disease patients to receive hemodialysis (HD) treatment. The maturation failure rate of AVFs is approximately 23%. The aim of our study is to compare intraoperative fistula flow and measurements of vascular structures' diameters with postoperative fistula maturation, following the completion of the fistula operation, to reveal the relationship between them. Providing insights into the need for intraoperative intervention and/or postoperative fistula management based on these measurements is intended to contribute to the literature by offering predictions and perspectives.
The aim of this prospective, randomized, blinded clinical superiority trial is to establish intraoperative placement of biodegradable stents in the pancreatojejunostomy as a safe, effective, and feasible preventive measure against pancreatic fistula following pancreatoduodenectomy. The investigators hypothesize that intraoperative placement of biodegradable stents in the pancreatojejunostomy is safe and can reduce the risk of pancreatic leakage following pancreatoduodenectomy in patients who have not undergone PBD.
The objective of this prospective，multi-center，single arm study is to obtain further data on the safety and performance of the Acotec Orchid＆Dhalia Drug-coated Balloon catheters for the treatment of for the obstructive lesions in the native Arteriovenous Dialysis Fistulae (AVF).
This is a prospective, multi-center, two-arm, randomized trial to quantify the performance of the EchoMark®/EchoSure® System for AVF diagnostic ultrasound when used under a protocol of biweekly use for assessing fistula maturation and reducing time to Clinical Maturation.
